Claims.

This invention relates to improvements in finger nail files, whereinmeans associated with the file are provided for dislodging accumulationsfrom under the finger nails, the said accumulations ordinarily beingreferred to as dirt.

In the employment of ordinary means for removing accumulations fromunder the finger nails, the dirt is forced into a mass under the nailsand its removal becomes more troublesome than is the case if the dirt iscutaway Or removed piece-meal and before it can be compressed ahead ofthe instrument used when cleaning the nails. Hence, it is an object ofthe invention to provide an attachment for finger nail files which willaccomplish the removal of the dirt without compressing it.

It is a further object of the invention to provide the said means foraccomplishing the foregoing results at the point of such files, and thesame has proven simple in character, efilclent and satisfactory in use,and comparatively inexpensive.

With the foregoing and other objects in view, the invention consists inthe details of construction, and in the arrangement and combination ofparts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to theaccompanying drawing forming part of this application, wherein likecharacters denote corresponding parts in the several views, and inwhich:

Figure 1 illustrates a view in perspective of a fragment of a fileshowing a cleaning instrumentality embodying the invention appliedthereto;

Figure 2 illustrates a perspective view showing fragments of theinstallation detached;

Figure 3 illustrates the utility of the invention in removing dirt; V

Figure 4 illustrates the manner in which the dirt is piled or compressedunder the finger nail in an attempt to remove it by the use of anordinary nail file; and

Figure 5 illustrates a plan view of a file with modified cleaning meansformed as a part of files now in common use.

In the present embodiment of the invention a nail file I is shown ashaving a dirt removing means at its end which comprises a length of wiredoubled on itself to form a loop 8 the ends 9 of which wire embrace theedges of the file at its outer. end, and preferably the end of the fileis reduced to form shoulders [0, against which the ends 9 of the wireabut; it being shown that the end of the file is reduced in width sothat the wire embracing the said end may be secured in position by aclamp or clip ll surrounding the assembled parts, and the clamp may bepressed into place or secured in any suitable manner, as by spot weldingor the like. The wire is preferably of steel, such as piano wire, or thelike, and it has one surface ground so that it is approximatelysemi-circular in cross section and has cutting edges l2 and'l3. Theforegoing parts, it will be observed are substituted for the nailcleaning end of the ordinary nail file. It is shown that the length ofmetal or wire has the outline of an acute angle and is semi-circular incross section throughout its length. The curved surfaces of what may betermed the arms which extend from the loop oppose each other, whereasthe fiat surface of the fabricated member is on the outer surface of thesaid arms, and are perpendicular to a plane containing both arms of saidangle. It is seen from an inspection of Fig. 3 that the edge of thescraper operates to dislodge deposits from the finger nail and that thescrapings or deposits when dislodged escape through the spac inside ofthe angularly disposed portions of the scraper.

As a modification ofthe dirt cleaning device described, the end l4 of anordinary finger nail file may be stamped or cut away to form an openingtherein through which dirt dislodged from the finger nail escapes, andthe edges l5 and [6 of the end may be sharpened to form cutting edgeswhich will serve to dislodge dirt in much the same manner as thatresulting from the use of the first mentioned embodiment, and eitherform of this invention may be produced without materially adding to theexpense of finger nail files now ordinarily employed.

Figure 3 illustrates the action of the finger nail cleaner of theinvention when operating underneath and relative to the finger nail Hwhich is shown in cross section, whereas Figure 4 illustrates the actionof an ordinary nail file when acting on dirt as it is being removed fromsuch a finger nail I1.

I claim:

1. A nail cleaning instrumentality comprising a length of metal doubledon itself to form an approximately V-shaped loop, said metal beingapproximately semi-circular in cross section with a convex inner surfaceand a straight outer surface having scraping edges at the junction ofthe convex'and straight surfaces, and a member carrying the saidinstrumentality.

2. A nail cleaning device for dislodging scrapings from finger nailcomprising a length of metal fabricated to an acute angle, the materialbeing semi-circular in cross section throughout its length, the curvedsurfaces of the angularly disposed portions of the metal being adjacentto one another and the flat surface of each portion being the outersurface of said angle, which surfaces are perpendicular to a planecontaining both portions of said angle.

terial at the edge of the aperture being convex and the outer edge ofthe material at the point being straight, whereby scraping edges areformed at the junction of the said convex inner surface and the straightouter surface, as and for the purpose described.

4. A nail cleaning device formed of a loop of relatively fine wirematerial, one surface of said material being convex and the opposedsurface being straight, with scraping edges formed at the merger of theconvex and straight surfaces.

5. A nail cleaning device comprising a length of relatively fine wirematerial doubled on itself to form an approximately V-shaped loop, thematerial of the loop being angular in cross section, the apices of whichangles form scraping edges and the sides of the material forming theangles impinging and moving deposits from the finger nails as thecleaning device is manipulated.
